Step by step
Solved in 5 steps
- (Numerical) a. Define an array with a maximum of 20 integer values, and fill the array with numbers input from the keyboard or assigned by the program. Then write a function named split() that reads the array and places all zeros or positive numbers in an array named positive and all negative numbers in an array named negative. Finally, have your program call a function that displays the values in both the positive and negative arrays. b. Extend the program written for Exercise 6a to sort the positive and negative arrays into ascending order before they’re displayed.(Electrical eng.) a. An engineer has constructed a two-dimensional array of real numbers with three rows and five columns. This array currently contains test voltages of an amplifier. Write a C++ program that interactively inputs 15 array values, and then determines the total number of voltages in these ranges: less than 60, greater than or equal to 60 and less than 70, greater than or equal to 70 and less than 80, greater than or equal to 80 and less than 90, and greater than or equal to 90. b. Entering 15 voltages each time the program written for Exercise 7a runs is cumbersome. What method could be used for initializing the array during the testing phase? c. How might the program you wrote for Exercise 7a be modified to include the case of no voltage being present? That is, what voltage could be used to indicate an invalid voltage, and how would your program have to be modified to exclude counting such a voltage?(Statistics) a. Write a C++ program that reads a list of double-precision grades from the keyboard into an array named grade. The grades are to be counted as they’re read, and entry is to be terminated when a negative value has been entered. After all grades have been input, your program should find and display the sum and average of the grades. The grades should then be listed with an asterisk (*) placed in front of each grade that’s below the average. b. Extend the program written for Exercise 1a to display each grade and its letter equivalent, using the following scale: Between90and100=AGreaterthanorequalto80andlessthan90=BGreaterthanorequalto70andlessthan80=CGreaterthanorequalto60andlessthan70=DLessthan60=F
- Mark the following statements as true or false. A double type is an example of a simple data type. (1) A one-dimensional array is an example of a structured data type. (1) The size of an array is determined at compile time. (1,6) Given the declaration: int list[10]; the statement: list[5] - list[3] * list[2]; updates the content of the fifth component of the array list. (2) If an array index goes out of bounds, the program always terminates in an error. (3) The only aggregate operations allowable on int arrays are the increment and decrement operations. (5) Arrays can be passed as parameters to a function either by value or by reference. (6) A function can return a value of type array. (6) In C++, some aggregate operations are allowed for strings. (11,12,13) The declaration: char name [16] = "John K. Miller"; declares name to be an array of 15 characters because the string "John K. Miller" has only 14 characters. (11) The declaration: char str = "Sunny Day"; declares str to be a string of an unspecified length. (11) As parameters, two-dimensional arrays are passed either by value or by reference. (15,16)(List maintenance) The following letters are stored in an alphabet array: B, J, K, M, S, and Z. Write and test a function named adlet(), which accepts the alphabet array and a new letter as arguments, and then inserts the new letter in the correct alphabetical order in the array.(Data processing) A bank’s customer records are to be stored in a file and read into a set of arrays so that a customer’s record can be accessed randomly by account number. Create the file by entering five customer records, with each record consisting of an integer account number (starting with account number 1000), a first name (maximum of 10 characters), a last name (maximum of 15 characters), and a double-precision number for the account balance. After the file is created, write a C++ program that requests a user-input account number and displays the corresponding name and account balance from the file.
- (Data processing) Construct a three-dimensional weather array for a two-week time period. Include this array in a C++ program that displays the temperatures correctly in response to any of the following user requests: • Any day’s high and low temperatures • Average high and low temperatures for a given month • Month and day with the highest temperature • Month and day with the lowest temperature(Practice) a. Write output statements using cout that can be used to display values from the first, third, and seventh elements of each array declared in Exercise 2. b. Write a for loop that can be used to display values for the complete array declared in Exercise 2.This question has three parts a. Write a C function called find, which receives the following 3 parameters: an integer array, the array size, and a number to search for. This function searches for the number (passed via the third parameter), within the array (passed via the first parameter). If the number is found in the array, the index of the array element where the number was found is returned by the function. If the number is not found, the program returns the value -1. b. Explain which parameter passing approach you are using for the three parameters and why you are using that approach for each of the parameters. c. Write a C main program that creates an array, puts data into the array, and then calls your find function to search for a particular number. You decide on the contents and size of the array, and the number to search for. If the number is found in the array, your main program prints “found” to the screen. If it is not found, it prints “not found” to the…
- C Program Functions with 2D Arrays Write a function named displayElements that takes a two-dimensional array, the size of its rows and columns, then prints every element of a two-dimensional array. Separate every row by a new line and every column by a space. In the main function, write a program that asks for integer input to be assigned on a 3 x 3 array and call the function displayElements to print the contents on the next line. Input 1. Multiple lines containing integer each line Output R1C1: 1 R1C2: 2 R1C3: 3 R2C1: 4 R2C2: 5 R2C3: 6 R3C1: 7 R3C2: 8 R3C3: 9 1 2 3 4 5 6 7 8 9C language for solution Note: soution this program Use Array 1. Write a program to do the following: a. Write a Cover Page function to print the HW details passing the needed parameters and has no return. b. Write a function that gets student grades and ID (maximum number of students is 20) then the function has a switch statement to enable the user to choose one of the following operation: i. Call MaxMin function to find and print the maximum and minimum grades as well as their ID ii. Call function Average to return the average grade of the class. iii. Call mark function to print students ID, their grades, and marks (as in the below table) iv. Call Sort function to sort the student ascending or descending based on their grades. The program will repeat the operation tile the user wish to terminate the program. Note: Student's grades are between 0 and 100 (use data validation technique). • You will get zero if you don't use comments and print HW details (your name, course name, course…write a c++ program: Create an array with 11 integers, which will be randomly selected from the range of 0 to 100. Print the items of the array on screen as one line. Develop a function that takes the array as argument and perform these operations: -Find the minimum of array items and replace (swap) with first item of the array. -Find the maximum of array items and replace (swap) with last item of the array. -Find the average of array’s items and assign it to middle location of the array. The average of numbers should be calculated as an integer. (hint: static_cast<int>(float))
